4. "I'm King Of The World!"
An absolute box-office smash, James Cameron's Titanic wowed the world and helped to make Kate Winslet and Leonardo DiCaprio the huge stars that they are today. As successful as it was, even the most ardent Titanic fan will admit that the script is occasionally overly-sappy, and character Jack Dawson's scream from the bow of the infamous ship is possibly the corniest moment of the three-hour running period. Simply elated to be on board the ship, DiCaprio's Dawson stands with his arms aloft and bellows that he's "King of the world". His untimely end proves otherwise, but the line remains arguably Titanic's most famous.
